Abstract: This invention is an air induction system that enables an enhanced flow of temperature-controlled, magnetically influenced forced air to the air intake of internal combustion, turbine-type, and other engines having an air intake manifold. An interior air inlet is positioned in communication with a passenger compartment of the vehicle. Additionally, or alternatively, a plenum outlet is positioned in an HVAC plenum of the vehicle. An air supply duct extends between the interior air inlet and/or the plenum outlet and the air intake manifold supplies conditioned air to the air intake manifold. Performance may be enhanced with the positioning of magnets and/or an air diverter valve into the system. As a result of the enhanced flow of magnetically influenced air and the more steady state of the temperature of the inducted air, fuel consumption and air emissions levels are reduced.

Abstract: An absorbent article is provided with an absorbent composite including a plurality of discrete superabsorbent-containing entities arranged on a substrate. The superabsorbent-containing entities are imbricated, meaning that the leading edge of each entity overlaps the trailing edge of each successive entity. When the absorbent article becomes wet and the superabsorbent expands, the adjacent entities slide over each other and the degree of overlap is increased. Accordingly, the expansion of the superabsorbent article causes the “Z” directional thickness of the absorbent composite to increase, and the effect of the expansion on the longitudinal and lateral (“X” and “Y”) dimensions is minimized.

Abstract: A gas appliance, flue assembly, or vent adapter including an adjustable flow regulator which regulates the proportions and volume of dilution air and combustion products into the vent is disclosed. The flow regulator can be adjusted to allow a given appliance to exhaust vent gases through a range of different venting systems constructed from a wide range of materials. The appliance installer may adjust the appliance vent gases for a particular pre-existing or installed vent. The flow regulator also provides flow resistance which helps prevent backdrafting and the free escape of dilution air (which may be heated room air in some instances) through the vent to the outside atmosphere.

Abstract: A new high flow rate sampling device and methods for measuring fugitive gas emissions are provided. The high flow rate sampler comprises an air mover connected to a flexible hose for drawing in air near a process component, such as a pump, compressor seal, flange, or pipe thread connection. A second sample hose draws air from the opposing side of the process component at a flow rate low enough not to affect capture of the leak by the first sample hose. Air measured from the first sample hose will contain fugitive emissions from the process component being measured, as well as from other process components. Air measured from the second sample hose will contain only fugitive emissions from surrounding process components and can then be subtracted from the measurement from the first sample hose to obtain the leak rate from the process component in question.
